How to preserve query parameters in react-router v4

Question

Users redirected to my app after login (server on java), and they have url, which looks like this http://10.8.0.29:8083/html/?locale=RU&token=1c5c71f2-dcda-4a51-8cf6-f8

Answer 1

I switched off the hash router in this project, which preserves all parameters in route.
